Clean-Space pass: drop self-test, legacy unused handler, BISECT_MINIMAL branch, duplicate banner PNG, stale comments

Lean mode: also strip pipeline-demo encounter/resolve sprites

Add visual-mode dropdown on step 0 — live toggle between lean and full

URL-encode sprite paths so spaces in dev path don't truncate <img src>

Version-aware Gradio file route — /file= on 4.x, /gradio_api/file= on 5+

Default --keep-warm and add --stop-on-exit + safer launch for Gradio 4/5/6

Add ORACLES_VISUAL_MODE toggle — lean default, full enabled via --full or env var

Remove gr.skip diff — broke multi-yield generator handlers, blocking grimoire->trial transition

Drop demo_card_backdrop image — pipeline-demo panels use CSS only

Drop wizard-desk backdrop + open-book illustration — more HF load-time wins

Drop heavy backgrounds (parallax, grimoire texture, phase + scene backdrops) for HF perf

Performance sweep: gr.skip diff + memoize hot HTML helpers per click transition

Memoize hot HTML helpers and lazy-load image module sprites for faster transitions

Serve banner parallax PNG via /gradio_api/file= — drops ~270KB from every click response

Remove unsupported @import + register assets via set_static_paths

Revert to /gradio_api/file= URL pattern — Gradio 5 file route

Try /file= route for sprite URLs instead of /gradio_api/file=

Serve sprites via /gradio_api/file= instead of base64 — initial HTML drops ~95%

BISECT: temporarily swap build_app() with minimal probe via BISECT_MINIMAL=1

Pin Gradio 5.29.1 (last known-good HF Space version) + fastapi 0.112.2

Address Gradio 6 deprecation: set theme+css as Blocks attrs, not constructor args

Define demo at module scope so HF Space's hot-reload launcher applies theme+css

BISECT 1: temporarily disable theme + css to test if they break Gradio 6 iframe render

Disable Gradio 6 SSR — Node-proxy SSR stalls on the large data-URI HTML

Gradio 6 API migration: theme + css to launch(); drop show_api

Roll back to Gradio 4.44.1 to match local dev

Disable Gradio 5 SSR — hydration fails inside

Bump Gradio to 5.x and bind launch to

Force-backdrop on standalone oracle-narration
